5/7 +1/3
find the common denominator for both of the fractions
common denominator is 21
mutiply by 3 for 5/7
(5)(3)/(7/(3)= 15/21
mutiply by 7 for 1/3
(1)(7)/(3)(7)= 7/21
15/21+7/21
add the numerators
15+7= 22
denominator stays the same -21
Answer:
22/21 or 1 1/21
Answer:
Less than 7
Step-by-step explanation:
7x 5/8 = 4.375 or 4 and 3/8
hope it helps!
Yes, I believe that is correct.
Answer:
Assuming the cones are the same height, then
V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3
V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3
V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3
V1/V2 = 1/6.25 = .16
V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)
V2/V1=6.25/1 = 6.25
Answer:
The volume is 356
, which agrees with the second answer option listed.
Step-by-step explanation:
Recall that the volume of a pyramid is the product of the area of its base(B) times the pyramid's height (h), divided by three:

For our case, the area of the base "B" is the area of a square of side = 8 inches. That is the area B is:

Now we can include this value and the value of the pyramid's height (h=12 in) in the formula for the volume to give the answer:
